Possibly in fear that hackers will be able to find backdoors in the Intel Darwin version and allow OSX to run on PCs other than Macs, Apple has only posted the sources of Darwin for PPC for the latest version.

> because an OSS project sponsored by a company is not popular does not mean that it is lip service.

It does amount to lip service - ever heard of people bashing Apple and MacOSX?. No and why not?. Because all Apple has to do is say hey the kernel is open sourced and that basically shuts people up. Now what can real programmers do with Open Darwin - basically squat!.
